c40d858f02 Switches back to angular stuff at input resolution; ensures all S-Video modes work.
Now to roll back onto composite. Fingers crossed!

246b474a25 Removes ONE_BIG_LOCK, having effectively neutered it anyway.
Starts work on more explicit API usage validation. Maybe the issue isn't a race condition?

940e9e037e Adds first_scan to LineMetadata.
Also reorders `Line` fields to match `Scan` fields, just for visual consistency.

230b9fc9e6 Permits multiple simultaneous scan reading ranges.
Also updates the OpenGL scan target as per the latest movements of things.

72a8fef989 Switches to much more straightforward Line/LineMetadata storage.
Spoiler: covering this whole segment behind producer_mutex_ seems to resolve all output issues, so clearly the existing logic isn't functioning correctly. Making it simpler seems like a pretty obvious way to get to the bottom of that.
